Thanks brother! But I need the second script to play in parallel, so I call the second with the & option.
This is because every ping cannot wait for other pings to be completed, so the new question is will the function be played in parallel as the script did? Or is there anyway for launching the function in parallel?
we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?
while running that batch idle cpu time is about %60-65... (0 Replies)
Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)
Hi,
i have installed solaris 10 on t-5120 sparc enterprise.
I am little surprised to see load average of 2 or around on this OS.
when checked with ps command following process is using highest CPU. looks like it is running for long time and does not want to stop, but I do not know... (5 Replies)
Hello AlL,..
I want from experts to help me as my load average is increased and i dont know where is the problem !!
this is my top result :

Hi ,
I am using 48 CPU sunOS server at my work.
The application has facility to check the current load average before starting a new process to control the load.
Right now it is configured as 48. So it does mean that each CPU can take maximum one proces and no processe is waiting.

Hello
I have created next scritpt to do the next: chekp if host is alive. When the host down, launch telnet other equip to do checks.
When execute the script the load average of the machines increase. For example:

lpt
LPT(4) BSD Kernel Interfaces Manual LPT(4)NAME
lpt -- generic printer device driver
SYNOPSIS
device ppc
device ppbus
device lpt
DESCRIPTION
The current lpt driver is the port of the original lpt driver to the ppbus(4) system.
One purpose of this port was to allow parallel port sharing with other parallel devices. Secondly, inb()/outb() calls have been replaced by
ppbus function calls. lpt is now arch-independent thanks to the ppbus interface. See ppbus(4) for more info about the ppbus system.
The parallel port bus is allocated by lpt when the printer device is opened and released only when the transfer is completed: either when the
device is closed or when the entire buffer is sent in interrupt driven mode.
The driver can be configured to be either interrupt-driven, or to poll the printer. Ports that are configured to be interrupt-driven can be
switched to polled mode by using the lptcontrol(8) command.
Depending on your hardware, extended capabilities may be configured with the lptcontrol(8) command. With an ECP/ISA port, you can take
advantage of FIFO and DMA.
In order to retrieve printer info from /dev/lpt0, just apply the cat command to the device. If the printer supports IEEE1284 nibble mode and
has data to send to the host, you will get it.
FILES
/dev/lpt0 first parallel port driver
SEE ALSO ppbus(4), ppc(4), lptcontrol(8)HISTORY
This driver replaces the functionality of the lpa driver, which is now defunct.
BUGS
There are lots of them, especially in cheap parallel port implementations.
It is only possible to open a lpt port when a printer is connected and on-line, making it impossible to run lptcontrol(8) when there is no
printer connected.
This driver could still stand a rewrite.
